ETS-Lindgren's HI-2790B Calibration Comparison System complies with US Government (CDRH/FDA) requirements for evaluating calibration consistency of microwave oven survey meters used by oven manufacturers in compliance testing. The HI‑2790B is a complete system containing all of the equipment necessary to check microwave oven survey instruments and monitor the calibration stability of these instruments. This involves checking each instrument periodically to make sure that its response is within specification, and its calibration remains constant. This must not be confused with performance of absolute calibration or transfer calibration on the instrument.
